Frozen wind turbines contribute to power blackouts across Texas, at least 4 million without power

Officials said natural gas and coal generators also were freezing.

Frozen wind turbines are contributing to the power blackouts across Texas, amid the unprecedented winter storm in recent days.

Rolling blackout orders were issued Monday in an attempt to curb the loss of electricity during the storm.

Texas GOP Gov. Greg Abbott tweeted that "the ability of some companies that generate the power has been frozen."

He also said the problem included natural gas and coal generators.

The Electric Reliability Council of Texas says the power outages may last through Tuesday.

Almost 4.5 million Texans are out of power, according to poweroutage.us, with Houston and Galveston being the hardest hit.

The electricity council is telling residents in Texas – where temperatures are in the single digits – to turn down their thermostats to 68- degrees and shut off non-essential lights and appliances.

Some residents have even been stuck in their vehicles during the storm, reports CNN.
